What is PWMIC?


Recommended Posts

This is the volt reg chip that is designed to control Vcore

settings that come from BIOS.

 

Jack the Vcore on up in BIOS and this IC will increase

in temp also as it is part of the Vcore curcuit.

 

@zaubara..... nice linky ;) i'm not for sure if that's the

exact chip 'cause I can't get the #'s off mine at the

moment. it's covered with cooling hardware. But that

darn sure is the "type" of IC and it's functions.

Uhh ... well, trust Popcicle. :D

I only knew that it has something to do with the voltage regulation :) Thanks for clearing that up.

 

I'm going to reapply my CPU sink, because the CPU temp rushes 10°C up as soon as it is under load ... in case I find the IC, i'll post its number here :)

If a guy can get some good]/i] air flow around the right

side of the CPU socket (as the board is mounted the case)

the reading on the PWMIC chip will go scale down.

If a guy is running a weak fan on top of the CPU heatsink

there just isn't enough cooling benefit to this chip from residual

air flow. Or if a guy is using a larger heatsink that extends out

far enough to shield the PWMIC from airflow.

Then there are those of us with other types of cooling other

than air that need to give this chip some attention. As we push

the Vcore pretty hard.

Ambient temperatures mean a lot and heat within the case also if there are airflow problems.

@ sirfergy..... that 9800 throws a ton of heat. and the PWMIC

chip isn't very far away from it 'cause it's to the

right of the ZIFF socket. What could you do to

give that area some air flow?

Well, I actually use this fanless heatsink:

I have two low rpm case fans pulling air in from the bottom and the power supply fan sucking the air out from the top.

 

I also have the VGA Silencer for my 9800.

 

My entire goal has been as quiet a system as possible. Right now my HD is the loudest component.

the PWMIC reading for mine is around low 30s with the CPU around 35. sometimes the PWMIC would be under 30, around 28, and the fan speed number under it would be 0

Hi

 

I know this is an old thread, but I found out what PWMIC stands for

 

Pulse Width Modulator Integrated Circuit

 

Any other acronyms you also wanted to know, but were too embarrassed to ask :D , can be found here.
